Method for preparing asphalt cleaners capable of effectively removing residual asphalt

Abstract

The invention provides a method for preparing asphalt cleaners capable of effectively removing residual asphalt. The method includes adding, by weight, 5-10 parts of water into a container at first, then sequentially adding, by weight, 60-80 parts of surfactants and 30-50 parts of petroleum ether into the container and stirring the water, the surfactants and the petroleum ether for 3-5 min to obtain preliminary mixed liquid; sequentially adding, by weight, 15-32 parts of modified coconut acid diethanolamide and 9-12 parts of isopropyl alcohol into the preliminary mixed liquid and mechanically stirring the modified coconut acid diethanolamide, the isopropyl alcohol and the preliminary mixed liquid for 10-20 min to obtain mixed liquid; adding, by weight, 20-30 parts of diethylene glycol diethyl ether into the mixed liquid, uniformly mixing the diethylene glycol diethyl ether and the mixed liquid with each other, then sequentially adding, by weight, 6-15 parts of trichlorethene and 1-4 parts of potassium pyrophosphate into the mixed liquid and manually stirring the diethylene glycol diethyl ether, the mixed liquid, the trichlorethene and the potassium pyrophosphate to obtain the asphalt cleaners. The method has the advantages that good cleaning effects can be realized by the asphalt cleaners, the asphalt cleaners are high in utilization rate, low in cost and little in environmental pollution, and processes for preparing the asphalt cleaners are simple.

Description

technical field [0001] The invention relates to the technical field of cleaning, in particular to a preparation method of an asphalt cleaner capable of effectively removing residual asphalt. Background technique [0002] Bitumen is a product obtained after crude oil is processed. Its composition is extremely complex, composed of hydrocarbons of different molecular weights and their non-metallic derivatives, and has strong adhesion. Generally insoluble in water, but soluble in organic matter such as benzene and gasoline. [0003] In the road construction and petrochemical industry, the cleaning of asphalt containers and construction machinery surface during the experiment has attracted more and more attention from insiders. Asphalt material is a semi-solid or solid substance at room temperature, with good adhesion, but it can gradually transform into a fluid with the increase of temperature and the extension of heating time. The thicker asphalt in the container can be remove...

AI Technical Summary

Problems solved by technology

Asphalt material is a semi-solid or solid substance at room temperature, with good adhesion, but it can gradually transform into a fluid with the increase of temperature and the extension of heating time. The thicker asphalt in the container can be removed by heating , but there is still a layer of leaching on the wall of the container, which is difficult to deal with
